sql - 在 SQL Server2008 中运行 Access2003 的相同 SQL 时出现 SQL 错误

Question

我有以下用 Access 2003 编写的 SQL。现在，我必须使用 SQL Server2008 开发 prj，并在 SQL Server2008 上运行此 SQL 时出现错误，因为 Access 的 First() 函数无法在 SQL Server 2008 中识别。在 SQL Server 2008 年，我尝试了 TOP() 函数，但我仍然无法解决它。请帮我。

  SELECT DISTINCTROW TableA.TCode,                  
  TableA.DCode,                 
  TableA.DepCode,                   
  TableA.ShouhinCode,                   
  First(TableB.TName) AS TNameFirstRecord,                  
  First(TableC.LDepName) AS LDepNameFirstRecord,                    
  First(TableD.ThingType) AS ThingTypeFirstRecord,                  
  First(TableA.GoodsName) AS GoodsNameFirstRecord,                  
  Sum(TableA.Amount) AS AmountData,                 
  Sum(TableA.MoneyAmount) AS MoneyAmountData,                   
  Sum(TableA.DetailedMoneyAmount) AS DetailedMoneyAmounData,                    
  Sum(TableA.SummaryMoneyAmount) AS SummaryMoneyAmountData,                 
  TableA.POSNo                  
 FROM (

 INNER JOIN TableB ON TableA.TCode = TableB.TCode

  TableA.ShouhinCode

我认为您需要使用窗口功能

您将表替换为具有行号的版本

SELECT TableA.TCode,                  
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode,                   
    B.TName AS TNameFirstRecord,                  
    C.LDepNamee AS LDepNameFirstRecord,                    
    D.ThingType AS ThingTypeFirstRecord,                  
    A.GoodsNameAS GoodsNameFirstRecord,                  
    Sum(A.Amount) AS AmountData,                 
    Sum(A.MoneyAmount) AS MoneyAmountData,                   
    Sum(A.DetailedMoneyAmount) AS DetailedMoneyAmounData,                    
    Sum(A.SummaryMoneyAmount) AS SummaryMoneyAmountData,                 
    A.POSNo                  
FROM 
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableA) A                 
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableC) C ON A.DCode = C.DCode                
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableB) B ON A.TCode = B.TCode                   
    INNER JOIN (select row_number() over (partition by object_id ORDER BY Name DESC) as RowNumber, * from TableD) D ON A.DepCode = D.DepCode    

WHERE 
  A.RowNumber = 1 AND B.RowNumber = 1 AND C.RowNumber = 1 AND D.RowNumber = 1

GROUP BY A.TCode,                 
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode,                   
    A.POSNo                  
ORDER BY A.TCode,                 
    A.DCode,                 
    A.DepCode,                   
    A.ShouhinCode
